To all who: t it may concern:

Beit known that I, ALBI-:RT B. SCHUYLER, l the more rapid and ccrtnin.

a citizen of the United States, and n restent of Rochester, in the county of Monroe and. State of New York, have invented certain new and useful Improvements in Carburctcrs for Explosion-Engines, of which the ft'zllowinfJr is a specification. 1

his invention relates to carbureters for ex losion-engincs and like purposes..

the drawings, Figure 1 is a central vertical section on the line 1 1 of Fig. 2 through a carbnreter embodying this invention. Fig. 2 is a top plan view of the greater part of said device and a horizontal section throng i the collar 25, and F ig. 3 isan elevation of the adjustable cani. I

The carbureter has an outside casing 1, inclosing an inner casing 2. The space 3 between the two casings is employe! as an airinlet space, and vertical ribs 4, Fig. 2, at intervals connect the inner casing 2 and the outer casing 1. To the upper end of the iiiner casing 2 is attached the connection 5 for attachment to thc inlet of an explosi'ni-engine, and this connection may embody a supporting-rib 6 and a guide 7 for thc stein S of the air-inlet valve 9. The said inlet-valve' slides in a cylindrical casing 10,1having near its upper end a rino' of ports 11. A spring 12, pressing, prcferahlv, at onc end against the guide 7 and at the other against the piston or valve 9, tends to keep said valve depressed below the series of lports 1l. Depending from the valve 9 is the cup 13 vprefcrahlv containing the pad 14, of suitable material, 'such aslcather. This pad normally closes the uppler end of the oil-inlet 15 h v striking upont e top of a plntc 16, supported on a stem 17, through which said oil-inlet runs. If oil is upon the top of the plate 16 and the ad 14 strikes the plate suddenly, thc oil will e s lashed or spattered outward from thc neig borhood of the orifice and will strike upon the inner walls of the casinfY 2. In order to increase the exposure of the. oil 'to the current of incoming air, thc bottom of the casing 2`has a. circular orifice 1S. from which extends the ca e or perforated t'inphragni 19 to the edges o the plate 16, so that :my oil running 0H the plate 16 or splashed thcrcfrom will pass upon the cage :ind will be more or less distributed over its` surface. so

that the incoming air comes in contact with 55 much more oi the oil than heretofore has been known, :indIthercfox-c the evaporatiop 'less extent.

i of the oil andiits mixture with the air will bc The particular form of cage herein shown is bell-shaped, with its top foriumv by thc plate 16, which is perforated litvond the pad 14, as is also its` depenzling cylin.=iical portion. The oil-inlet l5 is c ntrollcj h va needle-valve stcni 20, normally pressed downward to cut off the inlet of oil by means of a spring 21 acting u on :i collar 22 on the stein of said needle-va vc. which stem has also :i guidi` 23 upon the caising of the carburcter and which is prcveni'cd from turning by means of :i kcy24, resting in a keV-slot in sait'. stein. Upon thel upper end (noA of the stein is a collar 25, having a lng 26 thereon, extending inward over thc carbUreter-body. A `ect-screw 27 upon thc upper threaded end of the stem 20 determines the height of the lug 26.

Upon the topof the casings 1 and 2 is the disk 2S, having perloiiitions 29, adapted to n register with the air-openings between the ribs 4. The said disk 2S is rotatable by Y i' grasping thc edge of the disk, and the openings 29 are so far apart that when turned to one position the air-openings between the two casings are closed, and when in another position the said air-openings are completely uncovered, and in intermediate positions the said a1r-openiiigs are covered to greater or hinged the curved bar 32, having a screw 33 passing through the saine and bearing upon the upper face of said disk 28. B v adjusting f I the screw 33 thc bar 32 may he raised to different angles ywith reference to the face of said ldisk 28. The lug 26, carried by thevalve-stein 20is ada ted to ninkc contact wi ithcbar32. B vt iisarrziugcnuiitiisthe The disk is held in position h v i di: 28 is turned to adjust the sup ily of nir ',i-

to ine carhurcter through thc air-c ninncls 3 the saine movement also through the bnr 32,

lug 26, and valve-stein 20 controls` the inlet il of oil to .the cnrbnrcter.

The operation of the device is as follows:

As'tlie suction occurs in the 'explosion-engine los cylinder that suction will raise the vulve-disk S) until said valve-disk passes to n point iihovc the ports 11. i drawn by theniovcincnt of the piston of thc cngiiic down through the oriliccs or nir-ports 2E), down through the channels 3. ani upward through the inner carburetcrhod v.

In this position nir will he i to Y g I f 'Y 842,429

striking upon the upper face of the plate 16 and upon the hydrocarbon thereon, turns said hydrocarbon ol the plate and into the surroundin space, spattering it upon the inner`walls o the casing 2 and upon the outer l surface of the cage 19. lVhen the next suction occurs, the air passing into the interior of the cage and upward through it will cause very rapid evaporation of the widely-distributed and eusive hydrocarbon, which mixed with air will pass upward through the ports 11 and on into the cylinder.

What I claim is- 1. In a carbureter, the combination with lthe casing having an air-inlet discharging into its bottom, and an outlet an oil-supply extending up into said inlet, a foi'aminated cage vxtending from the upper cud of the oilsupply across the air-inlet; the cent-ral portion of the cage around the oil-supply'being'iniperforate, a spring-depressed suctionvalve controlling the space above said eage ito the outlet and provided on its under side with a valve of greater diameter than the oil-discharge opening to strikel the oil on the imperfoi'ate top portion of the tage and splash it over the perforated portions.

2. The combination of a carburetor-casing, e. spring-actuated valvetliereiii adapted to be auton'iatitally opened by suction through said casing and having a supplementary valve thereon, an oil-inlet adapted to be i-.losed by said supplementary valve and terminating in a plate, a perforated diaphiagm extendingaeross the air-inlet and to the edges of said plate, the said suppleiiientary valve being of such area as to strike an extended inipcrforate surface on said pl'ate i to (lose the oil-inlet and also to distribute oil from said plate over said diaphragm.

3. 'lhe combination of a earbureter-cas: ing, a cylindrical valve-seat therein, a ring of y ports around the saine, a valve-disk adapted to move in said. seat from one side of said ports tothe other side thereof, a spring normally tending to prevent passage of air through said ports by moving said disk to `one of its positions, an oil-inlet in said casing, a perforated diaphragm covering the airinlet to said casing, and ii'ieansfor distributing oil from the oil-inlet over said diaphragm.

4. The combination of a cai'bureter-casing, an air-inlet thereto, an oil-inlet, a perforated diaphragm in said raising, means for distributing oil from the oil-inlet over said diaphragm, a voi-ticiilly-iiiovahle valve con- 5. The combination with the cylindrical Y carburetor-casing having an outlet to the engine in its upper portion an air-inlet and an oil-inlet in the lower portion, a spring-depreed suction-valve controlling the passage through the cylinder and provided on its lower side with a fixed stern having a diskvalve controlling the oil-discharge opening, aiplate around the opening from which the o is splashed by said disk-valve, and a foraniinated extension of said plate receiving the oil splashed from said plate and exposing it to the entering air.

6. A carbureter com rising a casing having. inner and outer wa ls, air-inlets extending down from the top of the casing between the two walls, to a bottoni air-inlet, a horizontall -turning ring-valve on top of the casing an controlling said air-inlets, an oil-supply pipe extending u into the bottoni of the easing and having a hell-shaped foraininated cage extending frm its upper end and inclosing the bottom air-inlet, 'a s ring-de discharging centrally on top of said cage and 'having a passage leading to one side of the casing, a rotary ring-valve on top of the casing and controlling the air-inlets, a vertical rod mounted in bearings on the side of the casing and having a needle-valve on its lower TOO IIO

end closing the oil-passage, a spring pressing the rod down, a projection on the upper end of the rod overhanging the air-valve; a cam on the air-valve to engage said projection and lift the needle-valve, 'a spring-depressed suction-valve in the inner casing provided with a valve on its lower side controlling the oil-discharge opening.
